Unfortunately, I do not own one of these beauties but eventually I plan on having one. I have used one twice and was totally in love with it. It is built like a tank, is very, very sharp and appeared to have no more distortion than a 28 mm f/2.0. Pop Photo did a test on it a while back and the only thing they didn't like about it was the price. It has a very different look when shot wide open. Clearly defined foreground and a very soft receding background. Jonathan Castner Photojournalist Denver
